Excel - Editable Control Should Use To Display My Spreadsheet In Application?
Aug 31, 2011I have a spreadsheet in excel with three headers:
Project Name The name of a project i'm working on.
Requested Role The job title/profession of the project employee. (example: mechanic, manager, engineer)
The name of the employee.When i click on the Person's name i want another page or tab (specific to this person) to appear showing details about them such as their name, job title, how long they worked, what project they are doing... etc. (similar to a Facebook profile)
When i click on the project name i want another page or tab (specific to this project) to appear showing details about it such as the requirements, the deadline, who is currently working on it... etc.
Furthermore, i would like to set up two levels of access:For the specific pages i was thinking of using the tab control but i want it so that i can search through the list of projects or names, select one, and then it brings up the page about it.The levels of access is the least of my worries.
Taking To Long To Display Excel Spreadsheet On Datagrid?
Jan 11, 2010I have the following in my little program:A form containing a button and a combo box where each item is a "year" ex. 2009,2010,2011...
When the user selects an item from the combo box, and clicks a button, an excel spreadsheet is displayed in a datagrid.
- Depending on the item selected, a different file is opened.
Now, my problem is as follows. Every time the user press the button, it takes like 50 seconds to open the file and display it in the datagrid.
- The file range is from A1 to J393 (a lot of cells)
The procedure reads every cell from A1 to J393 and puts it in a multidimensional array. Therefore, I would like to know if there is a way to speed up this process.Another thing, lets say I selected year=2009 and press the button.I wait 50 seconds approx.Displays the spreadsheet (corresponding to the year 2009) on the datagrid.
Then
I select year=2010 and press the button.
Wait another 50 seconds approx.
Displays the spreadsheet (corresponding to the year 2010) on the datagrid.

DataGridView - Exporting Info To Excel Spreadsheet
Nov 10, 2011I have a datagridview which I would like to be able to export the information to an Excel spreadsheet, and be able to reload the information later on from a specified worksheet.

View 7 RepliesHow To Import Excel Spreadsheet To Bound DataGridView
Jul 21, 2009I'm trying to import an excel spreadsheet to a bound datagridview. I have a second form which I do all the importing from and update Form1's datagrid view. This part works great. Now, I am trying to update the table that the DGV is bound to, but cannot seem to get it. I know it is probably a simple Update command (which I've tried) but everything fails. It is confusing to me because I create a second dataAdapter and dataSet to import to, then set the BindingSource of the DGV to this new ds. Ideally, I want the Bound table to be empty, then require the user to import on the first run. After that, the imported list would always load.
Here is the code I use to import to the DGV and it works:
vb.net
Dim ds As New DataSet
Dim da As OleDbDataAdapter
Public Sub importDBButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles importDBButton.Click
OpenFileDialog1.InitialDirectory = ""
OpenFileDialog1.Title = "Select the Excel File to import from"
OpenFileDialog1.Filter = "Excel(*.xls)|*.xls"
[Code] .....
My DGV on the first form has a manually added column at index 0 that is a simple graphic. Not sure if this is causing errors, but thought I'd mention it. The spreadsheet that is imported is only 2 columns of the DGV. Do I have to specify data for the other columns? (There's about 16 and I didn't want to have to require the user to fill all that data out in the spreadsheet). How to save this imported data to the bound table?

View 8 RepliesForms - SQL Data To Excel Spreadsheet
Dec 24, 2009So I need to create a windows form that is able to generate reports by querying a SQL Database or SQL Server. There is data in the databases that will be put into an excel file from whatever columns from a specific table I need. I need it to be a dynamic query that is probably hard coded into the application because I might need to write other queries at some point to generate different reports that need different columns.
What I need is somewhere to start or some code that I can look at because im not very familiar when it comes to vb.net/excel. I need code to get all that data from the database and put it neatly in an excel file and I would like to specify what columns in the excel file all the data goes under.

View 1 RepliesManipulating Mutiple Excel-like Spreadsheet Data In .NET
Apr 21, 2009I have an project which was written in VB6 and made use of the Spread3.0 component to display multiple large data from database in spreadsheet. My objective is to convert this project into a VB.NET current version which would not use the third party component but can possibly use a freeware that does similar if not all the functionality.
My question is, are there any freeware that is available in .NET for such spreadsheet-like manipulation of data programatically? I have come across dsoFramer but this only allows the display of the data in an IE frame. I would like to jus embed the content into my existing form.
Also this freeware must be able to handle formula and user-editing as well as multiple cell type such as combobox/checkbox etc.

Takes Data And Writes It To A MS Excel Spreadsheet?
May 25, 2007I have a program that currently takes data and writes it to a MS Excel spreadsheet. (automatically opens the program, creates the cells, and fills them with data)
I would like to add an additional feature to my program that offers support for OpenOffice.org's 'Calc' spreadsheet program. (so users without MS Excel can use the application) So I am basically asking if anyone knows how to automate OpenOffice 'Calc' from VB.net. (I am using Visual Studio 2005)
I have searched on the OpenOffice forums but no one seems to know the vb.net code for this. So I was wondering if anyone here has done this, or would know how to do this.
OleDbException Saying Spreadsheet Is Full When Inserting To Excel Spreadsheet
Nov 11, 2011I have a VB.Net program that reads in a flat file, and then parses line by line, formatting the data into different spreadsheets in an excel workbook (each line can be any 10+ different record types so I parse and put in appropriate excel sheet).
For smaller sized flat files (under 10mb), the parser works great. However, I am trying this on a file that is over 120mb (400k+ lines). While running, I will get an OleDBException saying that the spreadsheet is full. Now I am pretty confident that Excel can handle a much larger data set than a flat file. So I assume this exception is not giving me the true story as to what is really occuring.
I open a connection, and then parse each line in the file, inserting each row into the excel file. I assumed it would be bad performance wise to open/close the connection between each insert. Could this be causing the issue? Any ideas what I need to do to handle such a large file? There are cases where the flat file can be over 500mb.
To actually do the insert into excel, I am just doing the following (I construct an sql query based on the type of row and values parsed):
Dim conn As New OleDbConnection()
conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + ExportLocation.Text + "" + importFileName + "-PVF.xls;Extended Properties=""Excel 8.0;HDR=YES"""
